In addition to having double pane windows, one of the things you should also take note of is the windows orientation. The orientation as well as the size can play a big part in the cost of heating and cooling your home.

To take full advantage of the natural light that windows permit, keep in mind that in the mornings, the sun is in the east and in the evening, in the west. Windows located on the west side of the home often become very hot during the summer months.

In midday the sun is often in the south and in the winter farther south. This makes windows located on the south, an excellent source of winter heat.

The north side of the house rarely receives direct sunlight and may be a good location for the bedroom windows.
